_D_e_s_c_r_i_p_t_i_o_n:

     Returns a list containing the survival curve, confidence limits
     for the curve, and other information.

_U_s_a_g_e:

     summary.survfit(object, times, censored=F, scale=1, ...)

_A_r_g_u_m_e_n_t_s:

  object: output from a call to 'survfit'. 

   times: vector of times; the returned matrix will contain 1 row for
          each time. This must be in increasing order and missing
          values are not allowed. If 'censored=T', the default 'times'
          vector contains all the unique times in 'fit', otherwise the
          default 'times' vector uses only the event (death) times. 

censored: logical flag: should the censoring times be included in the
          output? This is ignored if the 'times' argument is present. 

   scale: rescale the survival time, e.g., if the input data to
          'survfit' were in days, 'scale=365.25' would scale the output
          to years. 

     ...: other unused arguments

_V_a_l_u_e:

     a list with the following components

_S_e_e _A_l_s_o:

     'survfit', 'print.summary.survfit'.

_E_x_a_m_p_l_e_s:

     data(ovarian)
     summary( survfit( Surv(futime, fustat),data=ovarian))
